Spectrum Health completes 200th diagnostic procedure for lung conditions using robotic technology


GRAND RAPIDS, MI — Spectrum Health physicians recently completed their 200th procedure using robotic technology to diagnose early-stage lung cancers, officials say.

The integrated health system’s use of a robotic bronchoscopy platform has resulted in the diagnosis of 20 percent more cases, according to an Oct. 12 news release. This improves patient outcomes by providing access to earlier treatment options with more accuracy.

Two years ago, Spectrum Health introduced Auris Health’s Monarch Platform, an innovative endoscopy tool. More recently, physicians have combined this with Phillips’ Cone Beam CT technology and augmented fluoroscopy to help diagnose with high precision.

“We are equipped with the two leading technologies in the market. By combining these two highly innovative technologies it will allow us to reach any area of concern with unprecedented accuracy,” said Dr. Gustavo Cumbo-Nacheli, director of bronchoscopy and interventional pulmonology for Spectrum Health.

“Soon we will have the ability not only diagnose a suspicious lesion, but also treat these lung nodules during the same procedure. This revolutionary technology is designed to allow physicians to diagnose small peripheral lung nodules with high accuracy, using advanced imaging with a less invasive approach, offering a better experience for our patients.”

While University of Michigan’s Metro Health uses similar technology, there are key differentiators that set Spectrum Health’s apart, says Cumbo-Nacheli.

Metro Health’s Ion robotic catheter, like the Monarch used by Spectrum Health, allows a physician to reach further into the lung with control. However, the Monarch provides uninterrupted vision for the physician which allows less room for error. The Ion does not have this feature.

The combined technologies of the Monarch and Cone Beam CT allow physicians to analyze a 360 degree and three-dimensional image of a nodule, providing a patient with the most accurate diagnosis and treatment plan.

New measurements of the solar spectrum verify Einstein’s theory of General Relativity

An international team of researchers led by the Instituto de Astrofísica de Canarias (IAC) has measured, with unprecedented accuracy, the gravitational redshift of the Sun, a change in frequency of the lines in the solar spectrum which is produced when the light escapes from the gravitational field of the Sun on its way to Earth. This work, which verifies one of the predictions of Einstein’s General Relativity, is to be published in the journal Astronomy & Astrophysics.

The General Theory of Relativity, published by Albert Einstein between 1911 and 1916, introduced a new concept of space and time, by showing that massive objects cause a distortion in space-time which is felt as gravity. In this way, Einstein’s theory predicts, for example, that light travels in curved paths near massive objects, and one consequence is the observation of the Einstein Cross, four different images of a distant galaxy which lies behind a nearer massive object, and whose light is distorted by it.

Other well known effects of General Relativity are the observed gradual change in Mercury’s orbit due to space-time curvature around the “massive” Sun, or the gravitational redshift, the displacement to the red of lines in the spectrum of the Sun due to its gravitational field.

The gravitational redshift is an important effect for satellite navigation systems such as GPS, which would not work if General Relativity was not put into the equations. This effect depends on the mass and the radius of an

FCC moves forward in freeing up more midband spectrum for 5G




The Federal Communications Commission took its first big step toward freeing up 100 megahertz of wireless spectrum currently being used for the military and making it available for 5G service. On Wednesday, the agency adopted rules and proposed additional changes to the 3.3-3.55GHZ band of spectrum that’ll pave the way toward an auction of the spectrum to commercial service providers. 

This swath of spectrum has been used by the federal military. In August, the White House and Department of Defense determined it could be shared with commercial providers for 5G service. They urged the FCC to begin drafting rules for an auction to take place in December 2021. 

5G is the next generation of wireless technology rolling out across the world, promising to deliver much faster wireless service and a more responsive network. Its ability to connect more devices and offer real-time feedback is expected to spark a sea change in how we live and work, ushering in new advances like self-driving cars and advanced augmented reality experiences.

Midband spectrum, which is in the 2.5GHzz and 3.5GHz range of frequencies, provides more-balanced coverage and capacity due to its ability to cover a several-mile radius with 5G, despite needing more cell sites than lower-tiered spectrum bands. 

AT&T and Verizon didn’t initially focus on these spectrum bands for 5G and instead invested in millimeter wave spectrum — extremely high-frequency radio airwaves that offer essentially a souped-up Wi-Fi hotspot. 

But now these carriers are looking to use midband spectrum for 5G, especially as they seek to offer 5G to more suburban markets. 

“The FCC took another important step today in getting much-needed mid-band spectrum to market to fuel our country’s 5G future,” Will Johnson,
